If you want a certain race winner then you need a Richard Mac chassis like the one below  

But as Brumos say's, they are also metal and therefore not allowed either .

   

   

It would be just too easy ..........

[Kevan]

Not certain winners in our club, we see Mack chassied cars but there's plenty of alternatives that beat them...mostly plastic chassis too.

...but they're a guaranteed way to definitely improve an original basic chassied car

Its different when you are "live" racing, as a lot depends on the driver skills.

Graham, my ask is that you consider adding the 69 Camaro, Porsche 934 back in please. I’ve I just received a ton of parts and even opened a Porsche that’s been sitting since April ‘2021 and started building cars, I assume others may have started doing the same. 

On the wheels, I assume you are measuring at the rib and not the face as I’ve seen this complicate building in the past.  I suggest a simple 15x6 to 15x10 minimum size rule.  Unless the vehicle was equipped with a smaller diameter wheel. 

Just a comment regarding B&W chassis, if there are 10 cars with B&W chassis maybe consider it as a class on its own without a body restriction as with mounts the bodies are as heavy as other bodies.

I have restored the Porsche 934 & Camaro 69 to the list for you 

In the past you could have said that the "Richard Mack chassis " were commercially available, but sadly Richard does not seem to sell them anymore.

[Brumos RSR]

I picked up 2 this spring new from a distributor in the UK.  One Ferrari 250 GTO and one for the Autumn proxy in the form of a 79 Z/28.  It will be under powered due to the weight as a 25k motor has proven to be right.

You’re very lucky then, when I last saw him he did not seem to think he would be making more. I don’t know much about the process but I think his supplier of the laser cut parts has withdrawn their service. As it a very much a low volume specialist application, probably very difficult getting it done at a economic cost.

I think they are lighter than solid brass chassis, so probably run very competitive with a 23k motor.

[Kevan]

Depends how thick the brass is, Andy only uses 0.5mm thick brass which would be a fair bit lighter than a steel Mack jobbie.

Sorry but Not being very familiar with the Porsche 934, I checked it out this morning, and like the Porsche 911 RSR it has quite wide wheel arches compared to the other cars in this Category. So I think it is out of context of the other earlier cars in the " Monte Carlo -Sports car" category, and have moved it across to the "Tour de France - Touring Cars Category. It's now in the same list as the Camaro 69.
